Yes and speedo reads about 3-4 mph slower at 70 (used GPS to verify) with a stock 3.45 gear. Some dependency on tire height also. Fitment on the fronts is really more dependent on the rotor offset you are using. I originally had Brembos w aluminum hat which caused the tire to protrude past the front fender lip by maybe 1/2". Using the stock Z06 rotor however brings the tire flush w the fender. Besides using 18mm spacer (wheel and hub centric) you'll want to install
longer wheel studs. I got the GM studs for higher tensile strength.
